"A PROCESS FOR PRODUCING A COAL PELLET FROM COAL FINES."

A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 230 and 370 °C and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.

Iron Ore Agglomeration Technologies | IntechOpen

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...
